Was the sanitarium stabbing ever in the film?
Or did Hulme just write it so well that I think I saw it, lol? This is the scene where Sister Luke, coming to relieve the sister in the tub room one night, stops to gaze at the beautiful stars for a moment, so as to be exactly on time. As she enters the tub room it is eerily quiet, and for good reason. The sister, seated at her little desk, is slumped over it with a very large knife protruding from her back. Sister Luke rushes over to her as all the inmates watch in utter silence, and when she checks the pulse of the sister she finds she is still quite warm (& supple)--meaning she had been dead a fairly short time. Sister Luke adds this to her list of things to feel quilty about--maybe if her pride in punctuality hadn't slowed her down, she might have prevented it...
Apparently one of the tub inmates had, over time, worked a small hole in the canvas cover of his tub into a larger one with his toe, eventually getting enough of his foot into it on that fateful night to rip the cover sufficiently to get out of the tub & commit the murder. Don't remember anymore what the explanation about where the knife came from was, but the insane are often frightenly crafty...
The process of getting there is the quality of being there
